3.2.4.3.9 Application Requests Maximal Access Information of a File

To request maximal access information of a file being opened or created, in
addition to the parameters that are specified in section 3.2.4.3, the application
provides a Boolean indicating whether it is requesting maximal access
information of a file, and optionally a Timestamp value, in FILETIME
format as specified in [MS-DTYP]
section 2.3.3. If the application is requesting this information, the client
MUST construct an SMB2_CREATE_QUERY_MAXIMAL_ACCESS_REQUESTcreate context using the
syntax specified in section 2.2.13.2.5. The client appends it to any other
create contexts being issued with this CREATE request.
